Gather Data

Has there been testing for contamination, and did they find particular contaminants? Even without testing, maybe you know what kinds of chemicals were used on a particular site? Go to Public Data and find the CDC’s ToxFAQs. The CDC keeps information about each contaminant, and what kind of health problems each could cause. If the contamination that is known to be toxic, you don’t have to prove that it is causing health problems. Follow these links to learn more about air or soil and water quality testing.

Look up health data for your area on SfA’s Public Data page in the CDC WONDER database. Look especially for health problems associated with the kind of contamination you think is present. If you’re particularly concerned about cancer, see Guide to State Cancer Profiles.

A caution about using existing health data: Most government data is kept by county. If the contamination only affects a small number of people in a county with a large population, the government data won’t help you much. If the contamination affects most people in the county, though, it could be helpful.

Contact local hospitals and clinics to find out if there have been any changes in health problems over the period of time in question. Compare those data to hospital data from another area with no contamination. Hospitals may not want to give you information due to privacy issues. If that happens, contact public health researchers at a nearby college or university. Hospitals regularly provide data for academic research.

Explore Strategies

If you can’t find any data yourself, you might decide to conduct your own study. Start with the workshop A First Look at Health Studies. That workshop can help a group review the the major health study types and plenty of case studies, to make the decision about whether or not to pursue a study. If you do, and you’re not already connected to an environmental advocacy organization, you should consult with one before starting. The medical or public health school at a local university may also be able to conduct a study.

If you were able to get health data, you might need help interpreting it. Pieces of the Risk Puzzle can help you think about ways people might be exposed to contamination. You can compare disease incidence or prevalence rates to statewide or national averages using Compare to Standards.
